Maintenance Workflow
Data Import
- Geometry or surface data in virtually any ASCII format with a Text Import Wizard
- Versine
- Industry-standard LandXML geometry (horizontal, vertical, and cant) and surface data
Regression Analysis
- Horizontal and vertical alignments from survey data utilizing least squares computations
- Simultaneous regression of single or multiple elements with the Connection Editor
- Single element regression or heads-up point selection and automatic single-element regression
- Advanced multi-element regression with all supported element types (lines, circular arcs, and transition spirals)
- Validation of existing survey data based on user-specified criteria (minimum/maximum distance between points, angular differences, gradient differences, and so on)
- Conversion of surveyed rails to centerline
- Data selection and sorting
- Data editing for inclusion, exclusion, and weighting
- Rail Curvature Diagram
- Automatically generates transition points
- Inclusion of cant as an improved source of data for element determination
Design Validation
- Curvature diagrams and/or slew diagrams
- Plan and profile annotation
- XSL/XML reporting (horizontal alignment, vertical alignment, and cant )
Export to Field
- Plasser & Theurer tampers (ALC and WinALC systems)
- Matisa tampers (the PALAS system)
- Trimble
- Leica
- LandXML
Design Workflow
Interactive Geometry
- Robust sets of interactive geometry tools for on-screen alignment generation
- Tools using methods and principles specific to rail design and civil engineering
- Check Integrity tool for location and removal of alignment discontinuities
Horizontal Alignment
- Lines
- Circular arcs (arc and chord definition)
- Multiple spiral transition definitions, including:
- Clothoid
- Cubic parabola
- Bloss
- Biquadratic parabola
- Sinusoidal
- Cosine
- Viennese-Austria
Vertical Alignment
- Lines
- Parabola
- Circular arcs
- Vertical clothoid transition spirals
Cant
- Equilibrium equations ( Eq = 11.8 * V2 / R )
- Computation of equilibrium cant, applied cant, cant deficiency, rate of change of applied cant, rate of change of cant deficiency, and cant gradient
- ASCII tables
- Transitions
- Transitions that match the supported horizontal transitions
- Virtual transitions (where horizontal transitions are not required but cant is required)
- Design checks incorporated in editing
- Cant integrated into all horizontal curve edits
Turnouts
- Turnouts in the most popular configurations:
- Single branch
- Double branch
- Single slip
- Double slip
- Diamond crossings
- Support for multiple bending methods
- Swiss bending practice
- German bending practice
- UK tangent and offset practice
- Library of industry-standard turnouts
- German standards
- German light rail standards
- UK 113A and NR60 standards
- AREMA standards
- Tools for user-defined standards
- Interactive creation and editing
- Turnout Connection Editor for connecting turnouts and editing connections
Surface Modeling
- Profile Generator
- Easy profile creation across multiple surfaces
- Display and annotation of profiles and associated data such as vertical curves, superelevation diagrams, and digital terrain modeling (DTM) features
- Feature-based DTM
- Flexible, double-precision
- Intelligent features
- Representation and labeling of the DTM based on feature definition
- Proper display and labeling of terrain features throughout the model
- Typical Section Libraries
- Custom creation of typical sections for generating cross sections on the fly
- Cut/fill tables and decision tables for automatic adjustment of the model to predefined conditions
Interoperability
- Seamless integration between CAD platforms – in both DGN and DWG environments
- Integration with Bentley ProjectWise to bring collaborative design data to the entire project team in a secure environment
- Integration with Digital InterPlot, enabling automated plot set generation and Web-based access to plot archives
